2Claims.

This invention relates to washing machines for glassware, tumblers, beerglasses, and like receptacles, in which the receptacle is applied, byhand to fountain brushes and the flow of the cleansing fluid iscontrolled by the application of the glass to the washing or cleansingdevices.

The present application is a substitute for the application filed by meon the 27th day of June, 1938, under Serial Number 215,965.

The invention involves the use of a liquid detergent, sterilizer, orantiseptic, that is mixed with either not or cold water, under pressure,and means are provided for spraying both the interior and exteriorsurfaces of the glass, simultaneously, with the mixture or cleansingsolution. Internal and external brushes are employed in connection withthe cleansing liquid or mixture, and the brushing action is secured bytwisting the wrist of the hand which grasps the receptacle to be washed.

Means are also provided whereby the washed receptacle is finally rinsedby the use of clear water, and the rinsing is accomplished while thereceptacle still'remains immersed in the fountain portion of the washingmachine. The receptacle is thus sterilized, washed, and rinsed insuccessive steps in a single manually controlled operation, by immersionor submersion of the receptacle within the spray or fountain portion ofthe washing machine.

- The invention consists in certain novel combinations and arrangementsof parts as will hereinafter be more specifically set forth and claimed.In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention in which the parts are combinedand arranged according to one mode I have thus far devised for thepractical application of the principles of my invention, but it will beunderstood that changes and alterations may be made in theseexemplifying structures, within the scope of my appended claims, withoutdeparting from the principles of the invention.

- In the preferred form of my invention as illustrated in the drawings Iutilize a housing I of suitable size and shape, which is provided with2J0 a cover or closure 2 secured thereon in suitable manner. Within thehousing are formed an elevated liquid detergent chamber 3 having anupper screw plug 3 and a bottom wall 4, and the housing is also formedwith a cylindrical washing or brushing chamber 5 having an elevatedbottom 6.

The detergent reservoir 3 is provided with a vent opening V in its topwall formed by the closure 2 of the housing, and the washing or brushingchamber has a round opening in its top wall, also formed by the closure2, and this opening is provided with a rubber ring or gasket of.suitable material 1, of sumcient size to readily permit insertion ofthe glass Q into the washing chamber. The glass Q is grasped by thefingers and thumb in well known manner, inserted through the rubberring, held by the fingers and thumb while being washed and rinsed, andthen withdrawn. While the glass is immersed or submerged in the fountainsprays, it is given several turns by twisting the wrist, in order thatall parts metrically disposed brushes extending vertically within thechamber. In close proximity to these brushes T the chamber wall isprovided with four vertical series of spraying ports 8 extendinglaterally of the wall; so that the brushes are supplied with thecleansing solution, or with clear rinsing water, as desired. These portscommunicate with vertical duets or upright passages 9 in the wall of Forcleansing and rinsing the interior surface oi the immersed glass, Iprovide a central fixed, tubular post l2 having a base 13 that is fixedin suitable manner to the bottom of the washing chamber, above thedistributing chamber, and

the interior of this tubular post is open to the distributing chamber IIfor flow of cleansing solution or for flow of clear water. The tubularpost is fashioned with numerous lateral ports l4, and the exterior ofthe post is covered with tufts H to form a stationary brush conformingto the interior of the glass Q.

As indicated in Figures 1, '7, and 8 the exterior brushes T and theinterior brush l5 are closely related in order that the glass may bepushed down into the washing chamber; the depending rim or edge of theglass, as it is pushed down, separating the four exterior, brushes fromthe single interior brush; and when the glass has reached its fullydepressed position, the inner and outer brushes are in frictionalcontact with the wall of the glass.

The flow of washing solution is automatically controlled through the useof the glass as it is manually submerged or depressed within the washer,and for this purpose I employ a depressible, spring-lifted stem 16,located and supported within the tubular post, with its upper free endprojecting above the stationary brush IS. The free end of the stem iscapped with a rubber or resilient pad I! against which the inner face ofthe bottom of the glass contacts when the glass is inserted in thewasher, and by action of this contact the spring lifted stem isdepressed. when the cleansed and rinsed glass is withdrawn from thewasher, the spring-returned stem is automatically lifted to its initialposition as indicated in Figure 1.

The lower end of the stem passes through a hollow head or valve casingl8 that is attached at the undersideof the bottom 6 of the washerchamber, and the interior of this valve casing communicates with thedistributing chamber l I heretofore described.

0n the depressible stem and within the valve casing is mounted a solidcylindrical piston valve l9, which, as best seen in Figure 4, has alongitudinally extending port I9 opening above and below the piston, andthe upper end of this port is provided with a flexible disk, orflap-valve l9a that is attached to the stem and is adapted to close theport I! on the upstroke of the stem and open the port on the downstrokeof the stem. This auxiliary valve is adapted to control the flow of acharge of the liquid detergent, sterilizer, or antiseptic, which chargeis admitted to the valve casing by the piston valve, and then lifted tothe distributing chamber, as will be described.

The depressible valve stem is pushed down against the tension of aspring that is coiled about the lower end of the stem and interposedbetween a cap 2| fixed on the extremity of the stem and a stationarybase plate 22 that is supported from and below the valve casing, as byscrews.

The supply of water, either hot or cold, under pressure, is furnished tothe washer through the supply pipe 23. which opens into the interior ofthe valve casing just above the piston valve, when the latter is in itsdepressed or open position, as indicated in Figure 4.

The detergent reservoir 3 may be filled, when the screw plug 3' isremoved, by pouring the liquid in through the top filling hole, and theliquid detergent is suppliedby gravity from the bottom of the reservoirthrough the feed pipe 24. which communicates with the interior of thevalve casing just below the piston valve when the latter is in closedposition, or uplifted, as shown in Figures 1 and 2.

An outlet or drain for the washing chamber is provided by the drain pipe25, which as indicated in Figure 9 opens down through the bottom wall ofthe washing chamber.

An exterior gage 26, as best seen in Figure 1 is provided to indicate alow level of the liquid detergent in the reservoir 3.

As indicated in Figure 2 it will be apparent that while the piston valveis in uplifted position a charge of liquid detergent under gravity flowfrom the reservoir fills the valve casing below the piston valve, andthis charge is lifted or pumped up into the distributing chamber,through the upper end of the valve chamber, as the piston valve isdepressed. As indicated in Figures 3 and 4, the supply ofliquid'detergent is cut off by the descending piston valve, and itremains cut of! while the piston valve is in lowered or open position.

In Figures 2 and 3 the water supply to the interior of the valve casingis closed, and this supply is not opened until the piston valve reachesits lowermost or depressed position in Figur 4, and after the charge ofliquid detergent has been pumped into the upperpart of the valve casingor into the distributing chamber H.

With the piston valve in lowered or open position, the water, underpressure flows through pipe 23 into the casing and into the distributingchamber I l, thence through the tubular post and its ports, and alsothrough the radial ducts III to the ports of the brushes T, carryingwith it the liquid detergent in solution.

Under these described conditions, the flap valve l9ais held down orclosed on port I 9' by the water under pressure, and the supply ofdetergent remains cut off. Eventually the cleansing mixture is consumedin spray in connection with the two brushes, or the single inner brushand the set of outer brushes, and then, with the piston valve still openor depressed, clear rinsing water flows from the supply pipe 23 to thenumerous spraying ports 8 and H of the brushes.

As the rinsed glass is withdrawn from the brushes, and from .thevalve-stem, the latter is spring returned or lifted, moving the pistonvalve to closed position, and also closing, or holding closed the flapvalve l9a, thereby shutting off both the water supply and the supply ofliquid detergent from the distributing chamber,

After the glass has been withdrawn from the washing machine it may bedried in any suitable manner.

I claim:

1. In a glass washing machine having a distributing chamber, thecombination with a valve casing communicating with said chamber andhaving an inlet port, and a tubular ported post mounted above thecasing, of a spring-lifted depressible stem mounted in the post andprojectdetergent inlet port, ofa spring-lifted depressible stem passingthrough said chamber and casing, a piston-valve on the stem forcontrolling said ports, sald piston-valve having a port extendinglongitudinally. therethrough, and an automatic valve mountedi on thepiston valve adapted to open the last mentioned valve to permit flow ofacharge offthexdetergent to the distributing chamber ss-tne-piston-valve-stem is 10 depressed to open the water] inlet port.
